GENERAL DESCRIPTION

The AD8338 is a variable gain amplifier (VGA) for applications that require a fully differential signal path, low power, low noise, and a well-defined gain over frequencies from LF to 18 MHz. The device can also operate using single-ended sources if required. The basic gain function is linear-in-dB with a nominal gain range of 0 dB to 80 dB; the nominal gain range corresponds to a control voltage on the GAIN pin of 0.1 V to 1.1 V. The gain range can be adjusted up or down via direct access to the internal summing nodes at the INPD and INMD pins. For example, if a 47 ? resistor is applied to the INPD and INMD pins, a gain range of 20 dB to 100 dB is set with an input referred noise level of 1.5 nV√Hz.
